POLY ALUMINIUM CHLORIDE
[EIRI/EDPR/1018] (J.C.: 245US$,9657)
INTRODUCTION
Aluminium chloride hydroxide [1327-41-9], [10284-64-7], Alcl (OH)2 [14215-15-7], AlCl2(OH), produts, commonly known as polyaluminium chlorides (PAC) are used for a wide variety of industrial applications.
Other names for PAC are basic aluminium chloride, polybasic aluminium chloride, aluminium hydroxychloride, aluminium oxychloride and aluminium chlorohydrate. The presence of polymeric, aluminium-containing cations, the distribution of which can differ greatly, typifies PAC products.
Although the formation of polynuclear aluminium species in solution has been studied for over a century, there is still much controversy concerning aluminium polymerization reactions and the resulting product compositions.
Polyaluminium chloride is a partially hydrolyzed aluminium chloride solution, which may incorporate a small amount of sulphate, has been introduced in Japan, England and Australia as an alternative to alum.
Known as poly (aluminium chloride) or poly (aluminium hydroxy chloride is a member of the family of basic aluminium chlorides.
These are partially neutralized hydrates having the formula.
Al2Cl6-x(OH)x.6H2O Where x = 1.5
Polyaluminum chloride (PAC) is also called Aluminium chloride Hydroxide [1327-11-9]. Poly (aluminum chloride), PAC, has also an approximate empirical formula.
Al (OH)1.5 (SO4)0.125 Cl1.25 and is available as a solution with an aluminium content of 10 wt% expressed as Al2O3. It is an all-effective coagulant. It is reputed to provide faster flocculation and stronger flocs than alum in some applications.
Polyaluminum chloride is one of the significant inorganic flocculants. The most important inorganic flocculants are currently the trivalent salts of aluminum and iron as well as activated silica. Flocculants are used to optimize the separation of the solid phase from the liquid phase in aqueous suspension. These suspensions usually consist of organic or inorganic particles, which are of finely divided to colloidal consistency and are distributed in water as a dispersing medium. With smaller particles, the suspension is more stable i.e. the lower is the tendency for the particles to agglomerate and sediment.
However, addition of a flocculant drastically increases the rate of particle sedimentation so that a clear, supernatant liquid is obtained. The settled sludge can then be filtered rapidly or centrifuged, resulting in a more efficient separation.
Polyaluminium chloride, or PAC is made by partial hydrolysis of aluminum chloride to form a mixture of polymeric species. It is more expensive than alum on a weight basis, but has advantage over alum such as not lowering the pH as much and better cost-effectiveness in some applicaitons. Residual aluminum in the water is said ti be lower and performance in cold water is better. It is sold as a solution.
